Problems solved by technology
However, in some cases, such as the case of dry fingers, the contact area between the dry finger and the display screen is very small, and the recognition response area is very small, resulting in discontinuous collected fingerprints and easy loss of feature points, which affects the performance of fingerprint recognition

Abstract
The invention provides a fingerprint detection device, which is suitable for electronic equipment with a display screen to realize under-screen optical fingerprint detection, and comprises a microprism array arranged below the display screen; an optical assembly arranged below the microprism array; and an optical sensing unit array arranged below the optical assembly, wherein the optical sensing unit array comprises at least one optical sensing unit arranged below each microprism in the microprism array. Optical signals which are reflected by fingers and inclined relative to a display screen are converted into signals which are perpendicular to the display screen through the microprism array, so that the optical loss of the optical signals reflected by the fingers in the transmission process can be reduced, and the semaphore received by the optical sensing unit array and the fingerprint recognition effect are improved. In addition, since the thickness of the microprism array is generally small, it can be ensured that the thickness of the fingerprint detection device is small.
Description
technical field [0001] The embodiments of the present application relate to the field of fingerprint detection, and more specifically, to a fingerprint detection device and electronic equipment. Background technique [0002] With the rapid development of the terminal industry, people pay more and more attention to biometric technology, and the practical application of more convenient off-screen biometric technology, such as off-screen optical fingerprint recognition technology, has become a public demand. [0003] Under-screen optical fingerprint recognition technology is to install an optical fingerprint module under the display screen, and realize fingerprint recognition by collecting optical fingerprint images. With the development of terminal products, the requirements for fingerprint identification performance are getting higher and higher. However, in some cases, such as the case of dry fingers, the contact area between the dry finger and the display screen is very sm...
